Description
本發明係關於具備於左右鏈布之各一端部，具有嵌入體與被嵌入體之開離嵌插件之附有開離嵌插件之拉鏈，尤其是關於可藉由對前述被嵌入體進行2種嵌入操作，使前述嵌入體樞止之附有開離嵌插件之拉鏈。The present invention relates to a zipper provided with an open-release insert having an insertion body and an open-embedded insert of the embedded body at each end portion of the left and right chain cloths, in particular, two types of the above-mentioned embedded body can be used. The embedding operation causes the aforementioned insert to be pivotally attached with a zipper that is opened from the insert.
迄今為止，作為附有開離嵌插件之拉鏈之1種，已知有可將形成於左右一對鏈帶之一側之嵌入體，相對於形成於另一側之鏈帶之被嵌入體，在滑件之鏈齒引導路內通過，或直接通過滑件之側凸緣部及被嵌入體之側部，使嵌入體樞止於被嵌入體之任何人均可簡單地運用自如之附有開離嵌插件之拉鏈。該附有開離嵌插件之拉鏈之具體構成揭示於例如日本特開2008-43568號公報(專利文獻1)及國際公開第2010/109656號說明書(專利文獻2)。Heretofore, as one type of zipper with an open-release insert, it is known that an insert formed on one side of a pair of left and right chain belts can be inserted into the body of the chain formed on the other side. Passing through the sprocket guiding path of the slider, or directly passing through the side flange portion of the slider and the side portion of the embedded body, any person who pivots the insertion body to the embedded body can simply use it freely. Zipper from the insert. The zipper with the detachable insert is disclosed in, for example, Japanese Laid-Open Patent Publication No. 2008-43568 (Patent Document 1) and International Publication No. 2010/109656 (Patent Document 2).
根據專利文獻1及2，前述嵌入體具有一體形成於一側之前述鏈布之正反兩面之薄板狀嵌入板部，及形成於前述嵌入板部之鏈布端部側前端部之樞止部，而前述被嵌入體具有一體形成於另一側之前述鏈布之正反兩面且保持前述滑件之滑件保持部，及可樞止前述嵌入體之前述被嵌入部。前述被嵌入部具有經由階部，較厚地形成於前述滑件保持部之鏈布端部側，且從前述滑件保持部延設至鏈布端部側，進而向前述嵌入體側彎曲之大致J字狀內面，與可從前述被嵌入體之側部朝前述大致J字狀內面嵌入前述樞止 部之嵌入空間，且在前述J字狀內面具有自由轉動地支撐前述樞止部之嵌入板部嵌合凹槽。According to Patent Documents 1 and 2, the insert body has a thin plate-shaped inserting plate portion integrally formed on both sides of the chain cloth on one side, and a pivoting portion formed at a front end portion of the end portion of the inserting plate portion The embedded body has a slider holding portion that is integrally formed on the front and back sides of the chain cloth integrally formed on the other side, and holds the slider, and pivots the embedded portion of the insert body. The fitted portion has a thick portion formed on the end portion side of the slider holding portion via the step portion, and is extended from the slider holding portion to the end portion of the fastener fabric, and is further bent toward the insert body side. a J-shaped inner surface, and the pivoting portion can be embedded in the substantially J-shaped inner surface from a side portion of the embedded body The embedded space of the portion has an inserting plate portion fitting groove that supports the pivoting portion in a freely rotatable manner on the inner surface of the J-shape.
具有如上所述構成之附有開離嵌插件之拉鏈之構成為如先前之例如由日本實公昭59-25227號公報(專利文獻3)記載之側開型之開離嵌插件般，不僅可進行藉由從被嵌入體之側部嵌入，而使嵌入體樞止於嵌入部之第1樞止操作，亦可與具有插銷等之一般之開離嵌插件相同，藉由將嵌入體經由滑件之鏈齒引導路***至被嵌入體之第2樞止操作，使嵌入體樞止於嵌入部。藉此，專利文獻1及2所揭示之附有開離嵌插件之拉鏈，在使嵌入體樞止於被嵌入體以閉合拉鏈時，可任意選擇前述第1樞止操作及前述第2樞止操作。The zipper having the detachable inserts, which is configured as described above, is not only detachable, but also has a side-open type, which is described in Japanese Patent Publication No. 59-25227 (Patent Document 3). The first pivoting operation of pivoting the embedding body to the embedding portion by embedding from the side portion of the embedding body may be the same as the general opening and closing embedding device having a plug or the like, by inserting the embedding body through the sliding member The sprocket guiding path is inserted into the second pivoting operation of the embedded body to pivot the insertion body to the insertion portion. Therefore, the zipper with the release insert disclosed in Patent Documents 1 and 2 can arbitrarily select the first pivoting operation and the second pivoting when the insertion body is pivoted to the inserted body to close the zipper. operating.
因此，在使用專利文獻1及2記載之附有開離嵌插件之拉鏈時，對側開型之開離嵌插件之操作不熟練之情形，進行藉由將嵌入體經由滑件內***至被嵌入體而樞止於嵌入部之第2樞止操作，從而無需對開離嵌插件之操作費工夫，可順利地閉合拉鏈，又，在對側開型之開離嵌插件之操作熟練之情形，或逐漸熟練之情形，進行藉由從被嵌入體之側部嵌入，使嵌入體樞止於被嵌入部之第1樞止操作，從而可更容易地進行拉鏈之閉合。Therefore, when the zipper with the detaching insert shown in Patent Documents 1 and 2 is used, the operation of opening the detaching insert from the side opening type is unskilled, and the insertion body is inserted into the slidable body via the slider. The second pivoting operation of the embedding body is pivoted to the embedding portion, so that it is not necessary to operate the opening and closing of the inserting insert, the zipper can be smoothly closed, and the operation of opening the embedding insert of the opposite side is proficient. Or, in the case of gradual proficiency, the first pivoting operation of pivoting the insertion body to the fitted portion is performed by embedding from the side portion of the embedded body, whereby the zipper can be more easily closed.
再者，根據專利文獻1及2，分開拉鏈時亦與前述樞止操作時相同，使用者任意選擇使開離嵌插件拔脫之2種不同之操作中任意一種即可。因此，該等專利文獻1及2記載之附有開離嵌插件之拉鏈相較於目前之側開型附有開離嵌插 件之拉鏈，或具有插銷等之一般之附有開離嵌插件之拉鏈，其開離嵌插件之使用容易性大幅提高，且便利性及操作性優良，係對任何人均可簡單地運用自如之拉鏈。Further, according to Patent Documents 1 and 2, the zipper is also the same as the above-described pivoting operation, and the user can arbitrarily select any one of two different operations for opening and detaching the insert. Therefore, the zippers with the open-release inserts described in the above Patent Documents 1 and 2 are provided with open-release inserts compared to the current side open type. The zipper of the piece, or the zipper with the opening and inserting insert, which has a plug, etc., has a greatly improved ease of use of the open insert, and is excellent in convenience and operability, and can be easily used by anyone. zipper.
在閉合左右鏈帶之情形時，以第1樞止操作，將嵌入體之樞止部***至被嵌入體之被嵌入部。其次，使滑件滑動至被嵌入體之抵接於前述滑件保持部之鏈布端部側之階部的位置對接後，樞止部使嵌入至大致J字狀內面之嵌入體以樞止部為中心，經由狹縫朝被嵌入體轉動，藉此，將嵌入體之嵌入板部從滑件之側凸緣部之間隙***至滑件內部。此時，由於被嵌入體具有大致J字形狀，故嵌入體之樞止部在大致J字狀內面之嵌入板部嵌合凹槽穩定地樞止。When the left and right chain belts are closed, the pivoting portion of the insert body is inserted into the fitted portion of the embedded body by the first pivoting operation. Next, after the slider is slid to the position where the insert body abuts against the step portion of the end portion of the link holding portion of the slider holding portion, the pivoting portion pivots the insert body embedded in the substantially J-shaped inner surface The stopper is centered and rotated toward the embedded body via the slit, whereby the inserting plate portion of the insert body is inserted into the slider from the gap of the side flange portion of the slider. At this time, since the embedded body has a substantially J-shape, the pivoting portion of the insert body is stably pivoted in the fitting plate portion fitting groove of the substantially J-shaped inner surface.
第2樞止操作係將滑件滑動至被嵌入體之抵接於前述滑件保持部之鏈布端部側之階部的位置對接後，將嵌入體之嵌入板部從滑件之導入口***，並將嵌入體之樞止部嵌入至被嵌入體之被嵌入部。藉此，左右鏈齒排以進行穩定嚙合的方式予以定位。The second pivoting operation is performed by sliding the slider to a position where the insert body abuts on the end portion of the chain end portion side of the slider holding portion, and then inserts the insert portion of the insert body from the slider inlet. Insertion and embedding the pivoting portion of the insert into the embedded portion of the embedded body. Thereby, the left and right element rows are positioned in a stable engagement manner.
如此，使嵌入體***至滑件及被嵌入體之被嵌入部之滑件，於鏈齒嚙合方向滑動(上拉)，藉此，使左右鏈齒排相互嚙合從而閉合拉鏈。In this manner, the insert is inserted into the slider and the slider of the embedded portion of the embedded body, and is slid (pull-up) in the element meshing direction, whereby the left and right element rows are engaged with each other to close the zipper.
因此，相對於專利文獻1及2記載之附有開離嵌插件之拉鏈使拉鏈之開離嵌插操作變容易，例如，對於要求以單手進行拉鏈之操作之製品、無法直接目測開離嵌插件之位置而需試探地進行拉鏈之操作之製品、進而在難以進行精細 作業之環境下要求拉鏈操作的製品等，可更適宜使用專利文獻3所揭示之側開型附有開離嵌插件之拉鏈。Therefore, the zipper with the opening and closing insert described in Patent Documents 1 and 2 facilitates the opening and detaching operation of the zipper, for example, for a product requiring a zipper operation with one hand, it is not possible to directly visually open the detachment. The position of the plug-in and the need to tentatively perform the operation of the zipper, and thus it is difficult to fine In the case of a work requiring a zipper operation in the work environment, it is more preferable to use a side open type zipper with an open-release insert disclosed in Patent Document 3.

然而，前述專利文獻1及2記載之主要適用於服裝類或背袋類之附有開離嵌插件之拉鏈，近年亦適用於汽車之座椅或椅套等，在閉合拉鏈時，多數是藉由人體之移動等，施加強大之撕裂力，以使開離嵌插件側之左右鏈布端部向左右撕裂(在本申請案中，稱呼為反撕裂力)。又，在服裝類中，亦有不慎卡住等，從而有與前述同樣施加反撕裂力之情形。如此之反撕裂力係集中於左右鏈布及接合於各鏈布端部之正反面之薄片狀加強片之鏈布長度方向的前端緣，與沿著各鏈布端部之一側緣延伸之上述嵌入體及被嵌入體的各交叉部之一點而直接作用。However, the above-mentioned Patent Documents 1 and 2 are mainly applied to a zipper with an open-release insert attached to a garment or a bag, and in recent years, it is also suitable for a seat or a seat cover of a car, and when the zipper is closed, most of them are borrowed. A strong tearing force is applied by the movement of the human body or the like so that the ends of the left and right chain cloths that are opened away from the insert side are torn to the left and right (in the present application, referred to as a tearing force). Further, in the clothing category, there is also a case where it is inadvertently stuck, and the like, and the reverse tearing force is applied in the same manner as described above. Such a tearing force is concentrated on the front and rear edges of the left and right chain cloths and the longitudinal direction of the sheet-like reinforcing sheets joined to the front and back sides of the respective chain ends, and extends along one side edge along the end portions of the respective chain fabrics. The above-mentioned embedded body and one of the intersecting portions of the embedded body directly act.
其結果，包含薄壁之加強片，與前述嵌入體及被嵌入體之間之接合產生剝落之虞。其原因為若較大之反撕裂力集中作用於前述交叉部之一點，則因拉鏈之閉合，導致相互位置固定之前述嵌入體及被嵌入體處於樞止狀態，鏈布與接合於該鏈布之端部之正反面之加強片，會沿著鏈布長度 方向之前端緣於撕裂方向強力拉伸。即，牢固固著於相互位置不動之嵌入體及被嵌入體之左右鏈布及加強片因前述反撕裂力，沿著其前端緣於撕裂方向伸展，藉此，與嵌入體及被嵌入體之接合產生偏移，從而導致加強片與鏈布一起從前述嵌入體及被嵌入體剝離，很有可能導致拉鏈之破損。As a result, the reinforcing sheet including the thin wall is peeled off from the joint between the insert and the insert. The reason is that if a large reverse tearing force is concentrated on one of the intersections, the insert and the embedded body are fixed in a pivotal state due to the closure of the zipper, and the chain is bonded to the chain. The reinforcing sheet on the front and back of the end of the cloth will follow the length of the chain The front edge of the direction is strongly stretched in the tearing direction. In other words, the left and right chain cloths and the reinforcing sheets which are firmly fixed to each other and which are fixed to each other are stretched along the front end edge in the tearing direction by the tearing force, thereby being embedded in the body and embedded therein. The engagement of the body is offset, causing the reinforcing sheet to peel off from the aforementioned insert and the embedded body together with the chain cloth, which is likely to cause breakage of the zipper.
本發明係為解除如此之問題而完成者，其目的在於提供一種假設即使作用如上所述之強大反撕裂力，經由加強片於鏈布之端部之正反面接合一體化之嵌入體及被嵌入體，與前述加強片之間不會產生剝離，尤其是附有開離嵌插件之拉鏈。The present invention has been made to solve such a problem, and an object thereof is to provide an insert body and a joint which are assumed to be integrated with the front and back surfaces of the end portion of the chain fabric via the reinforcing sheet even if the strong tearing force as described above is applied. There is no peeling between the insert and the aforementioned reinforcing sheet, especially the zipper with the insert inserted away from the insert.
上述目的可藉由本發明之附有開離嵌插件之拉鏈有效地達成，該附有開離嵌插件之拉鏈之主要構成為於左右一對之第1及第2鏈布的對向側緣，具有插通滑件之左右一對之鏈齒排；在鄰接於各鏈齒排之端部之各鏈布之各端部，具有接合一體化的薄片狀加強片；且具備開離嵌插件，其具有沿著各加強片之側緣部固設之嵌入體，與可轉動地支撐該嵌入體，且亦作為前述滑件之下止擋發揮功能之被嵌入體；前述滑件具有引導柱、連結於前述引導柱之上翼板及下翼板、立設於前述上翼板及/或前述下翼板之左右側緣之側凸緣；前述被嵌入體具有可藉由從前述被嵌入體之側方嵌入而樞止前述嵌入體之被嵌入部而成者，且其特徵為前述嵌入體及前述被嵌入體之各自由端部越過各鏈布及各 加強片之鏈布長度方向之端緣，向鏈布長度方向突出，且閉合拉鏈時，在前述第1及第2鏈布及前述加強片之長度方向之各端緣，與前述嵌入體及被嵌入體之各自由端部之固著端緣的交叉部處，至少在通過前述嵌入體與第1鏈布之交叉部之該鏈布之前述交叉部的前述端緣，具有含1個以上折曲部之由2條以上連續直線形成之缺口部。The above object can be effectively achieved by the zipper of the present invention with an open-release insert, the main structure of the zipper with the open-release insert being opposite to the opposite side edges of the first and second links of the left and right pairs. a pair of left and right chain rows of the insertion sliders; each end portion of each of the links adjacent to the end portions of the element rows has a sheet-like reinforcing sheet integrally joined; and an opening and closing insert is provided The utility model has an insert body fixed along a side edge portion of each reinforcing piece, and an embedded body which rotatably supports the insert body and also functions as a lower stop of the slider; the slide member has a guide post, a side flange connected to the upper and lower wing plates of the guide post, and the left and right side edges of the upper wing plate and/or the lower wing plate; the embedded body has an insertable body The side is embedded and pivots the embedded portion of the insert body, and is characterized in that the insert body and the insert body are each ended over each chain and each The end edge of the reinforcing sheet in the longitudinal direction of the chain is protruded in the longitudinal direction of the chain fabric, and when the zipper is closed, the end edges of the first and second chain fabrics and the reinforcing sheet in the longitudinal direction are combined with the insert body and the Each of the inserts has an intersection of the end edges of the end portions, and at least one of the end edges of the intersection portion of the chain cloth passing through the intersection portion between the insert body and the first chain fabric has one or more folds The notch portion formed by two or more continuous straight lines of the curved portion.
根據較佳態樣，前述缺口部較佳為形成於前述第1及第2鏈布之包含對被縫製品之各縫製線之區域。According to a preferred aspect, the notch portion is preferably formed in a region of the first and second chain fabrics including the respective sewn lines of the sewn product.
又，根據較佳之態樣，前述嵌入體具有一體形成於前述第1鏈布之正反兩面之薄板狀嵌入板部，與形成於該嵌入板部之鏈布端部側前端部之樞止部；前述被嵌入體具有一體形成於前述第2鏈布之正反兩面上，且保持前述滑件之滑件保持部，與可樞止前述嵌入體之前述被嵌入部；前述樞止部具有經由階部，較厚地延設於前述滑件保持部之鏈布端部側，進而朝前述嵌入體側彎曲之大致J字狀內面，與可從前述被嵌入體之側部向前述大致J字狀內面嵌入前述樞止部之嵌入空間；同時，可將前述樞止部能夠自由轉動地樞止於前述大致J字狀內面。又，亦可將前述被嵌入體設為可藉由將前述嵌入體經由前述滑件之鏈齒引導路***而樞止。Further, according to a preferred aspect, the insert body has a thin plate-shaped inserting plate portion integrally formed on both the front and back surfaces of the first link fabric, and a pivoting portion formed at a front end portion of the end portion of the inserting plate portion The embedded body has a slider holding portion integrally formed on the front and back surfaces of the second chain cloth and holding the slider, and the embedded portion that can pivot the insert body; the pivot portion has a via portion The step portion is thickly extended on the side of the chain end of the slider holding portion, and further has a substantially J-shaped inner surface that is curved toward the insert body side, and is substantially J-shaped from a side portion of the insert body The inner surface of the inner surface is embedded in the insertion space of the pivoting portion; and the pivoting portion is pivotally locked to the inner surface of the substantially J-shaped shape. Further, the embedded body may be pivoted by inserting the insert into the element guide path of the slider.
更佳的是，前述折曲部具有2條直線，該等之直線折曲成直角或銳角均可。又，較佳為沿著前述鏈布之前述鏈齒排安裝芯線，於該芯線之端部形成前述樞止部，且保留位於該樞止部之形成區域之芯線部分，該鏈齒排端部側之一 部分具有經切割之第2缺口部，前述芯線部分之鏈布長度方向之長度設定為較前述第2缺口部之鏈布長度方向之長度短。More preferably, the bent portion has two straight lines, and the straight lines may be bent at a right angle or an acute angle. Further, it is preferable that a core wire is attached along the sprocket row of the chain cloth, the pivoting portion is formed at an end portion of the core wire, and a core portion at a forming region of the pivoting portion is retained, and the sprocket row end portion One of the sides The portion has a cut second notch portion, and a length of the core wire portion in the longitudinal direction of the chain is set to be shorter than a length of the second notch portion in the longitudinal direction of the chain.
又，在本發明中，較佳為於前述滑件保持部之對向於前述嵌入板部之側面，形成有可嵌合前述嵌入板部之嵌入板部嵌合凹槽，又，於前述嵌入部之前述大致J字狀內面之一部分，亦宜延長形成有前述嵌入板部嵌合凹槽。Further, in the invention, it is preferable that the side surface of the slider holding portion facing the inserting plate portion is formed with an fitting plate portion fitting groove into which the inserting plate portion can be fitted, and the embedding It is also preferable to extend the portion of the substantially J-shaped inner surface of the portion to form the fitting groove of the inserting plate portion.
本發明之附有開離嵌插件之拉鏈與上述專利文獻1及2記載之拉鏈相同，可進行2種不同之樞止操作：第1樞止操作，將嵌入體從被嵌入體之側部嵌入，樞止於被嵌入體；及第2樞止操作，將嵌入體經由滑件之鏈齒引導路***至被嵌入體，從而樞止於被嵌入體。The zipper with the detaching insert of the present invention is the same as the zipper described in Patent Documents 1 and 2, and can perform two different pivoting operations: the first pivoting operation, embedding the insert from the side of the embedded body And pivoting to the embedded body; and the second pivoting operation, inserting the insert into the embedded body via the sprocket guiding path of the slider, thereby pivoting to the embedded body.
在本發明中，如上所述，進而至少具有上述缺口部係作為最具特徵之構成。藉由具備該特徵構成，可有效地減少對鏈布之長度方向端緣與嵌入體及被嵌入體之交叉部作用之強大之反撕裂力。作為該缺口部之具體態樣，係形成於通過前述交叉部之鏈布之鏈布長度方向之各端緣的例如具有矩形狀或階段狀般之1個以上之折曲部，尤其較佳為具有2條以上之直線，並將該等之直線折曲成直角或銳角，在2條以上之直線上切割形成缺口部。若形成缺口部，則假設即使沿著鏈布之鏈布長度方向之各端緣部，對座椅或衣服等之被縫製品，施加朝向外側之強大之撕裂力，該撕裂力亦不會直接傳達至前述交叉部，而經由前述鏈布之開 離嵌插件側端緣之對被縫製品之縫製線上之縫紉線施加。In the present invention, as described above, at least the above-described notched portion is configured as the most characteristic. By having such a characteristic configuration, it is possible to effectively reduce the strong ripping force acting on the longitudinal end edge of the chain cloth and the intersection of the insert body and the embedded body. The specific aspect of the notch portion is formed by, for example, one or more bent portions having a rectangular shape or a step shape at each end edge of the chain fabric in the longitudinal direction of the chain fabric passing through the intersection portion, and particularly preferably There are two or more straight lines, and the straight lines are bent into a right angle or an acute angle, and the notches are formed by cutting on two or more straight lines. When the notch portion is formed, it is assumed that a strong tearing force toward the outside is applied to the sewn product such as a seat or a garment even at each end portion along the longitudinal direction of the chain fabric, and the tearing force is not Will be directly transmitted to the aforementioned intersection, and opened through the aforementioned chain cloth It is applied to the sewing thread on the sewing line of the sewn product from the side edge of the insert.
此時經由縫紉線傳達之反撕裂力，首先傳達至前述缺口部之折曲部，在該折曲部，前述反撕裂力之一部分被分散，且經分散後之前述反撕裂力之一部分傳達至前述交叉部。前述折曲部為例如90°以上之鈍角之情形時，該折曲部未發揮緩衝功能，從而導致撕裂力直接傳達至前述交叉部，產生如前文所述之問題。At this time, the tearing force transmitted through the sewing thread is first transmitted to the bent portion of the notch portion, and at the bent portion, one part of the tearing force is dispersed, and the aforementioned tearing force is dispersed. A part is conveyed to the aforementioned intersection. When the bent portion is, for example, an obtuse angle of 90 or more, the bent portion does not function as a cushioning function, so that the tearing force is directly transmitted to the intersection portion, causing a problem as described above.
形成如上所述之缺口部之結果，係使得傳達至前述交叉部之反撕裂力減少。即，由於最初強大之反撕裂力每依序經過1個以上之折曲部分散減少後，使最終減少之反撕裂力傳達至前述交叉部，故即使強大之反撕裂力施加至鏈布之長度方向端緣，亦不會產生對於嵌入體及被嵌入體與加強片間之接合之剝離，從而防止拉鏈之破損。As a result of forming the notch portion as described above, the tearing force transmitted to the intersection portion is reduced. That is, since the initial strong tearing force is reduced by each of the more than one portion of the bent portion, the final reduced tearing force is transmitted to the aforementioned intersection portion, so even a strong tearing force is applied to the chain. The end edge of the cloth in the longitudinal direction does not cause peeling of the joint between the insert and the embedded body and the reinforcing sheet, thereby preventing breakage of the zipper.
通常，如上所述，施加至被縫製品之上述反撕裂力係經由上述第1及第2鏈布之對被縫製品之各縫製線上之縫紉線，沿著拉鏈之鏈布長度方向端緣施加。此處，如先前所述，於鏈布之長度方向之端緣，未形成本發明之上述缺口部時，係使反撕裂力沿著前述端緣集中並直接作用於上述交叉部之一點。但如本發明般，若於包含前述縫製線之區域形成上述缺口部，則經由被縫製品之縫紉線傳導至前述交叉部之反撕裂力不會干預缺口部內之接縫部分，主要干預實際縫製有無該缺口部之被縫製品與鏈布之接縫。由於實際縫製有該被縫製品與鏈布之接縫之位置與缺口部分離，故經由該接縫施加之反撕裂力經由缺口部之上述折曲 部傳導至上述交叉部，從而藉由前述折曲部使應集中於一點之反撕裂力確實分散，有效地減少傳達至前述交叉部之反撕裂力之大小。Generally, as described above, the above-mentioned rip-off force applied to the workpiece to be sewn is via the sewing threads on the respective sewn lines of the sewn products of the first and second chain fabrics, along the longitudinal end edge of the fastener chain. Apply. Here, as described above, when the notch portion of the present invention is not formed at the edge of the longitudinal direction of the fastener, the tearing force is concentrated along the end edge and directly acts on one of the intersections. However, according to the present invention, if the notch portion is formed in the region including the sewing line, the tearing force transmitted to the intersection portion via the sewing thread of the stitched product does not interfere with the seam portion in the notch portion, mainly intervening in practice. The seam of the sewn product and the chain cloth of the notched portion is sewn. Since the position where the seam of the sewn product and the chain cloth is actually sewn is separated from the notch portion, the tearing force applied through the seam is bent through the notch portion. The portion is transmitted to the intersection portion, so that the rip-back force concentrated at one point is reliably dispersed by the bent portion, and the magnitude of the rip-back force transmitted to the intersection portion is effectively reduced.
又，於鏈布之寬度方向端緣添設有芯線。另一方面，由合成樹脂材料成形之上述嵌入體及被嵌入體以經由加強片包覆前述芯線之表面的方式而成形一體化。通常，芯線之厚度較鏈布之厚度厚，且在芯線之安裝部位，向鏈布之表面直線狀凸出。另一方面，尤其是前述嵌入體之嵌入板部，由於必須能夠容易地插通形成於對方之被嵌入體之側部，故厚度必須較狹縫寬度薄，且其正反面均為平滑。使前述嵌入體之正反面為平滑面不得不使包覆芯線表面之部位之嵌入板部之厚度更薄，從而更弱體化。因此，如上所述，若對上述交叉部施加強大之撕裂力，則包覆前述嵌入板部之芯線表面之部位容易斷裂，且容易產生嵌入板部與加強片之間之偏移，很可能喪失作為拉鏈之作為開離嵌插件拉鏈的功能。Further, a core wire is added to the end edge of the chain fabric in the width direction. On the other hand, the above-described insert body and the body to be molded which are formed of a synthetic resin material are integrally molded so as to cover the surface of the core wire via a reinforcing sheet. Usually, the thickness of the core wire is thicker than the thickness of the chain cloth, and linearly protrudes toward the surface of the chain cloth at the mounting portion of the core wire. On the other hand, in particular, the inserting plate portion of the above-mentioned insert body must be easily inserted into the side portion of the insert body of the other body, so that the thickness must be thinner than the slit width, and both the front and back surfaces thereof are smooth. The smooth surface of the front and back surfaces of the insert body has to be made thinner in the thickness of the portion of the plated portion covering the surface of the core wire, thereby making it weaker. Therefore, as described above, when a strong tearing force is applied to the intersection portion, the portion covering the surface of the core wire of the inserting plate portion is easily broken, and the offset between the embedded plate portion and the reinforcing sheet is likely to occur, which is likely to occur. Loss of function as a zipper to open the zipper of the insert.
在本發明中，如上所述，由於在前述芯線之端部形成前述樞止部，且保留位於該樞止部之形成區域之芯線部分，該鏈齒排端部側之一部分具有經切割之第2缺口部，故使得該第2缺口部由嵌入板部之成形材料填滿，該部位厚度比嵌入板部之其他部位厚，與上述缺口部產生之功能互起作用，在受到反撕裂力之影響之部位，嵌入板部之強度進一步提高，從而不會產生斷裂等之不良，可長期穩定地使用作為附有開離嵌插件之拉鏈。In the present invention, as described above, since the pivoting portion is formed at the end portion of the core wire and the core portion at the forming portion of the pivoting portion is retained, one of the side portions of the end portion of the sprocket has a cut portion Since the notch portion is formed, the second notch portion is filled with a molding material embedded in the plate portion, and the thickness of the portion is thicker than other portions of the insertion plate portion, and interacts with the function of the notch portion to receive a tearing force. In the affected portion, the strength of the embedded plate portion is further increased, so that defects such as breakage do not occur, and the zipper with the open-release insert can be used stably for a long period of time.
以下，一面參照圖式，一面列舉實施例詳細地說明本發明之實施形態。再者，本發明並不限定於以下說明之各實施例，只要為具有與本發明實質性相同之構成，且發揮相同之作用效果，則可進行各種之變更。例如，在下述實施例中，雖就藉由將合成樹脂射出成形而形成鏈齒及開離嵌插件之拉鏈進行了說明，但本發明並不限定於此，例如，亦可為於鏈布安裝有線圈狀之鏈齒或金屬製之開離嵌插件之拉鏈。Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings.

Stereo picture. Furthermore, in the following, in order to explain the present invention more easily, the slider 30 with the open-release insert shown in Fig. 1 will slide the slider 30 along the length of the chain so that the slide fastener 1 is closed. The direction (upper in FIG. 1) is defined as the front, and the direction in which the zipper 1 is slid (the lower side in FIG. 1) is defined as the rear. Further, when the zipper 1 is viewed from the front, the side in which the insert 10 that is opened from the insert 5 is formed in the width direction of the chain cloth 2 is defined as the left side, and the side on which the embedded body 20 is formed is defined as the right side. square. Further, the direction orthogonal to the front and back surfaces of the chain cloth is defined as the height direction, and the dimension of the direction is expressed by the thickness.
如圖1所示，本實施例1之附有開離嵌插件之拉鏈1具備左右一對第1及第2鏈布2a、2b；列設於第1及第2鏈布2a、2b之對向側緣之鏈齒3；鄰接於左右鏈齒排4之下端部設置 之開離嵌插件5；及滑件30。As shown in Fig. 1, the slide fastener 1 with the release insert of the first embodiment includes a pair of left and right first and second chain fabrics 2a and 2b, and a pair of first and second chain fabrics 2a and 2b. To the side edge of the sprocket 3; adjacent to the lower end of the left and right sprocket row 4 Opening the insert 5; and the slider 30.
前述第1及第2鏈布2a、2b沿著對向之側緣，具有較鏈布膨大狀(較厚)之芯線7，沿著包含該鏈布2之芯線7之鏈齒安裝緣部，隔以一定間隔，列設有複數個鏈齒3而構成鏈齒排4。各鏈齒3具有固定於左右鏈布2a、2b之本體部；從本體部向鏈布外側延伸之頸部；及設置於頸部之前端之膨大狀之嚙合頭部；例如，可藉由將迄今為止一般使用之聚縮醛等之合成樹脂材料射出成形為特定形狀，安裝於各鏈布2a、2b。The first and second chain cloths 2a and 2b have a core line 7 which is relatively bulky (thicker) than the side wall of the opposite side, and along the element mounting edge portion of the core wire 7 including the chain cloth 2, A plurality of sprocket teeth 3 are arranged at regular intervals to form a sprocket row 4. Each of the fastener elements 3 has a body portion fixed to the left and right chain cloths 2a, 2b; a neck portion extending from the body portion toward the outside of the chain cloth; and an inflated engaging head portion disposed at the front end of the neck portion; for example, A synthetic resin material such as polyacetal which has been conventionally used is injection-molded into a specific shape and attached to each of the chain fabrics 2a and 2b.
前述滑件30可使用迄今為止一般所知者，具有例如，上翼板31a；下翼板31b；沿著上翼板31及下翼板31b之左右側端緣，配置於正交方向之上下側凸緣32a、32b；以由導入口側連結上翼板31a與下翼板31b的方式立設之引導柱33；安裝於上翼板31a上之拉片34。因此，於滑件30之內部，形成從嚙合口向導入口分支成2股之Y字狀鏈齒引導路。再者，在本發明中，前述滑件30亦可為例如於上翼板31a及下翼板31b之任意一者之左右側端緣，立設有側凸緣部者。The slider 30 can be used as conventionally known, and has, for example, an upper blade 31a; a lower blade 31b; and a left and right edge along the upper blade 31 and the lower blade 31b, disposed above and below the orthogonal direction The side flanges 32a and 32b are guide pillars 33 that are erected so as to connect the upper blade 31a and the lower blade 31b from the inlet side, and the tabs 34 attached to the upper blade 31a. Therefore, inside the slider 30, a Y-shaped sprocket guide path branched into two strands from the meshing port guide inlet is formed. Furthermore, in the present invention, the slider 30 may be, for example, a left and right side edge of either one of the upper blade 31a and the lower blade 31b, and a side flange portion may be provided.
於鏈布2a、2b之下端，將薄片狀之加強片15接合於鏈布之正反面並一體化，前述加強片15以裹住芯線7的方式，在該鏈布側緣折返，接合於正面側與反面側。雖在各鏈布2a、2b各接合(接著)有1片加強片15，但亦可在正反面採用2片加強片。又，亦可僅接合於正面或反面中之一者。At the lower end of the chain cloths 2a, 2b, the sheet-like reinforcing sheets 15 are joined to the front and back surfaces of the chain cloth and integrated, and the reinforcing sheets 15 are folded around the side edges of the chain cloth so as to wrap around the core wires 7, and joined to the front side. Side and back sides. Although one reinforcing sheet 15 is joined (and subsequently) to each of the chain fabrics 2a and 2b, two reinforcing sheets may be used on the front and back sides. Moreover, it is also possible to join only one of the front side and the back side.
如圖2分解所示，前述開離嵌插件5以連接於鏈齒排4之 形態，使合成樹脂製之嵌入體10與被嵌入體20對向而設置於在第1及第2鏈布2a、2b之各後端之加強片15上。As shown in the exploded view of FIG. 2, the aforementioned opening and closing insert 5 is connected to the element row 4 In the form, the synthetic resin-made insert 10 is placed on the reinforcing sheet 15 at the respective rear ends of the first and second chain fabrics 2a and 2b so as to face the embedded body 20.
前述嵌入體10具有沿著左右鏈布對向之側緣，一體形成(固設)於第1鏈布2a之下端部之正反兩面上之薄板矩形狀之嵌入板部11；形成於嵌入板部11之鏈布後端側前端部之樞止部12；於嵌入板部11之正反面，沿著鏈布內側(相比設置鏈齒排4之鏈布側緣更靠近鏈布之表面側)之側面形成之凸條部13；及在嵌入板部11之前端部連續形成為鏈齒排4之嚙合部14。The insert body 10 has a rectangular plate-shaped inserting plate portion 11 integrally formed (fixed) on the front and back surfaces of the lower end portion of the first chain cloth 2a along the side edges of the right and left chain cloths; The pivoting portion 12 of the front end portion of the rear end side of the chain portion 11 is located on the front and back surfaces of the inserting plate portion 11 along the inner side of the chain fabric (the side surface of the chain cloth is closer to the side surface of the chain cloth than the side edge of the chain cloth 4 The ridge portion 13 formed on the side surface; and the end portion before the insertion of the plate portion 11 is continuously formed as the meshing portion 14 of the sprocket row 4.
又，在本實施例1中，形成有嵌入體10之第1鏈布2a，係如圖3所示，鏈布後端緣之中央部接合於鏈布之正反面，且包含薄片狀之加強片15被切成矩形狀，形成缺口部16。前述嵌入板部11之後端自由端(與鏈齒排4側相反之側)越過第1鏈布2a之後端緣向後方突出，且該嵌入板部11之固著端緣之後端左側側面，與第1鏈布2a及加強片15之後端大致交叉成直角，形成本發明之交叉部A(圖7)。前述嵌入板部11除上述凸條部13以外正反面均為平坦，且鏈布正反方向之厚度形成為較設置於滑件30之上下側凸緣32a、32b間之間隙之間隔小。Further, in the first embodiment, the first chain cloth 2a of the insert body 10 is formed, and as shown in Fig. 3, the center portion of the rear end edge of the chain cloth is joined to the front and back surfaces of the chain cloth, and includes a sheet-like reinforcement. The sheet 15 is cut into a rectangular shape to form a notch portion 16. The rear end of the inserting plate portion 11 at the rear end (the side opposite to the side of the element row 4) protrudes rearward beyond the end edge of the first chain cloth 2a, and the left end side of the rear end of the fitting end portion of the inserting plate portion 11 is The first link 2a and the rear end of the reinforcing sheet 15 are substantially crossed at right angles to form the intersection A of the present invention (Fig. 7). The inserting plate portion 11 is flat except for the above-mentioned ridge portions 13, and the thickness of the chain cloth is formed to be smaller than the gap between the lower flanges 32a and 32b provided on the slider 30.
如圖2所示，嵌入板部11之下端部具有樞止部12，圓柱形狀之軸部12a從該樞止部12之正反面突出。該軸部12a係形成為鏈布正反方向之厚度小於滑件30內部之鏈齒引導路之高度方向之間隔，即小於滑件30內部之上翼板31a與下翼板31b間之間隔，且大於設置於上下側凸緣32a、32b間 之間隙間隔。As shown in FIG. 2, the lower end portion of the inserting plate portion 11 has a pivoting portion 12 from which a cylindrical shaft portion 12a protrudes from the front and back surfaces of the pivoting portion 12. The shaft portion 12a is formed such that the thickness of the chain cloth in the front-rear direction is smaller than the height direction of the sprocket guiding path inside the slider 30, that is, smaller than the interval between the upper flap 31a and the lower flap 31b of the slider 30. And larger than between the upper and lower side flanges 32a, 32b The gap interval.
前述凸條部13係形成為較嵌入板部11更厚。如此厚度之凸條部13沿著鏈布內側側緣形成，藉此，可提高嵌入體10之強度，進而對於操作開離嵌插件5之使用者而言容易把持嵌入體。The ridge portion 13 is formed to be thicker than the insertion plate portion 11. The ridge portion 13 having such a thickness is formed along the inner side edge of the chain fabric, whereby the strength of the insert body 10 can be improved, and the user can easily hold the insert body for the user who operates the detachment insert.
於第1及第2鏈布2a、2b之對向側緣部，分別添設有芯線7。由於芯線7厚度較鏈布2厚，故若在形成有芯線7之部位由合成樹脂成形具有平坦之表面之嵌入板部11，則會使形成於芯線7上之部分之嵌入板部11之厚度極薄。如此，若使嵌入板部11之厚度局部變薄，則該較薄之部分之強度極度變小，例如如後所述，對第1鏈布2a之後端緣作用將拉鏈撕裂般強大之力(反撕裂力)時，第1鏈布2a及接合於該鏈布2a之後端部表面之薄片狀加強片15伸展，與此同時，嵌入板部11之前述較薄部分很可能斷裂。由於將產生上述不良之嵌入板部之表面整體設為平面，故如上述專利文獻1所示，亦可於嵌入板部之配置芯線之表面位置設置凹陷部。A core wire 7 is attached to each of the opposite side edges of the first and second chain fabrics 2a and 2b. Since the thickness of the core wire 7 is thicker than that of the chain fabric 2, if the inserting plate portion 11 having a flat surface is formed of synthetic resin at the portion where the core wire 7 is formed, the thickness of the portion of the inserting plate portion 11 formed on the core wire 7 is made. Very thin. When the thickness of the embedded plate portion 11 is partially thinned, the strength of the thin portion is extremely small. For example, as will be described later, the end edge of the first chain cloth 2a acts as a force to tear the zipper. (Tear tearing force), the first chain cloth 2a and the sheet-like reinforcing sheet 15 joined to the end surface of the chain cloth 2a are stretched, and at the same time, the aforementioned thin portion of the inserting plate portion 11 is likely to be broken. Since the entire surface of the inserting plate portion in which the above-described defect occurs is a flat surface, as shown in the above Patent Document 1, a recessed portion may be provided at a surface position of the core wire in which the plate portion is placed.
上述被嵌入體20具有經由加強片15形成於第2鏈布2b之正反兩面之滑件保持部21；經由加強部25及階部22，較厚地形成於該滑件保持部21之後端，且具備大致J字狀內面24及嵌入空間28之被嵌入部23；較滑件保持部21更形成於鏈布內側，用於提高被嵌入體20之對鏈布2之固著強度之加強部25；沿著對向於上述嵌入板部11之滑件保持部21之側面及前述大致J字狀內面24之一部分而形成之嵌入板部 嵌合凹槽26；與嵌入板部嵌合凹槽26連通，從前述被嵌入部23之外周面貫通至大致J字狀內面24之可插通嵌入板部11之狹縫27。該狹縫27之鏈布正反方向之槽寬設定為較嵌入板部11之厚度大，以便能夠插通前述嵌入板部11。The embedded body 20 has a slider holding portion 21 formed on both the front and back surfaces of the second chain cloth 2b via the reinforcing sheet 15, and is formed thicker at the rear end of the slider holding portion 21 via the reinforcing portion 25 and the step portion 22, Further, the substantially J-shaped inner surface 24 and the embedded portion 23 of the embedded space 28 are provided; the slider holding portion 21 is formed on the inner side of the chain cloth for enhancing the fixing strength of the pair of the cloths 2 of the embedded body 20 a portion 25 formed along a side surface of the slider holding portion 21 facing the inserting plate portion 11 and a portion of the substantially J-shaped inner surface 24 The fitting groove 26 communicates with the fitting plate portion fitting groove 26, and penetrates from the outer peripheral surface of the fitted portion 23 to the slit 27 of the substantially J-shaped inner surface 24 that can be inserted into the fitting plate portion 11. The groove width in the front-rear direction of the slit of the slit 27 is set to be larger than the thickness of the inserting plate portion 11 so as to be able to be inserted into the above-mentioned inserting plate portion 11.
前述滑件保持部21係其鏈布正反方向之厚度形成為小於滑件30內部之鏈齒引導路之高度，而大於設置於上下側凸緣32a、32b間之間隙之間隔。又，滑件保持部21之嵌入體對向側緣彎曲成其中間部位僅向嵌入體10略微凸出。再者，如後所述，滑件保持部21使滑件30滑動對接至階部22時(參照圖5)，會***至滑件30之鏈齒引導路內而保持滑件30。The thickness of the fastener holding portion 21 in the front-rear direction of the fastener is formed to be smaller than the height of the fastener guide path inside the slider 30, and larger than the interval between the gaps provided between the upper and lower flanges 32a and 32b. Further, the opposite side of the insert body of the slider holding portion 21 is curved so that the intermediate portion thereof is slightly convex only toward the insert body 10. Further, as will be described later, when the slider holding portion 21 slides the slider 30 to the step portion 22 (see FIG. 5), it is inserted into the element guide path of the slider 30 to hold the slider 30.
在本實施例1中，由於前述被嵌入部23形成為介隔階部22厚度較滑件保持部21厚，且從滑件保持部21越過鏈布後端向外側突出延伸，並從其前端向嵌入體10側彎曲，故正視時呈現大致J字形狀。又，該被嵌入部23具有可從被嵌入體20之側部嵌入嵌入體10之樞止部12之嵌入空間28，及抵接嵌入至該嵌入空間28之樞止部12而可自由轉動地樞止之大致J字狀內面24。大致J字狀內面24之曲率半徑係形成為與嵌入體10之軸部12a之半徑大致相等。In the first embodiment, the embedded portion 23 is formed such that the thickness of the intervening step portion 22 is thicker than that of the slider holding portion 21, and protrudes outward from the rear end of the chain cloth from the slider holding portion 21, and from the front end thereof. It is bent toward the side of the insert 10, so it has a substantially J-shape when viewed from the front. Further, the embedded portion 23 has an insertion space 28 that can be fitted into the pivot portion 12 of the insert 10 from the side of the embedded body 20, and is rotatably attached to the pivot portion 12 that is fitted into the insertion space 28. The substantially J-shaped inner surface 24 is pivoted. The radius of curvature of the substantially J-shaped inner surface 24 is formed to be substantially equal to the radius of the shaft portion 12a of the insert 10.
再者，根據本實施例1，與第1鏈布2a相同，於安裝有被嵌入體20之的2鏈布2b之後端緣中央部，形成有作為本發明最具特徵之反撕裂力減低機構之矩形狀之缺口部16。Further, according to the first embodiment, as in the first chain cloth 2a, the center portion of the end edge after the attachment of the two-chain cloth 2b of the embedded body 20 is formed with a reduction in the tearing force which is the most characteristic feature of the present invention. The rectangular notch portion 16 of the mechanism.
上述所有構成，除缺口部16以外，基本上與上述專利文獻1及2記載之附有開離嵌插件之拉鏈並無實質性改變，但 在本實施例1中，與專利文獻1及2之附有開離嵌插件之拉鏈不同之構成如前文所述，為於第1及第2鏈布2a、2b之附有開離嵌插件側之端部即後端緣中央部，形成有本發明之反撕裂力減低機構，即包含矩形狀或階段狀之折曲部與2條以上之直線之缺口部16。此處，缺口部16較鏈布及加強片之前述交叉部A之後端(下端)更向鏈布長度方向凹陷而形成，從交叉部A之後端緣，向於左右方向從A脫離之方向，連接至後端緣後，形成缺口部16。All of the above configurations are substantially different from the zipper with the open insert described in Patent Documents 1 and 2 except for the notch portion 16, but In the first embodiment, the constitutions of the first and second chain fabrics 2a and 2b are attached to the side of the inserting and inserting side, as described above. The end portion of the rear end edge, that is, the center portion of the rear end edge, is formed with the tearing force reducing mechanism of the present invention, that is, a notched portion 16 including a rectangular or stepped bent portion and two or more straight lines. Here, the notch portion 16 is formed to be recessed in the longitudinal direction of the chain fabric from the rear end (lower end) of the intersection portion A of the chain cloth and the reinforcing sheet, and the direction from the rear edge of the intersection portion A to the left-right direction from A is After being connected to the rear end edge, the notch portion 16 is formed.
再者，在本實施例1中，如圖4及圖7所示，在添設有第1鏈布2a之芯線7之側之側緣部，保留位於前述嵌入體10之固設區域之後端之芯線端部7a，將固設有嵌入體10之區域整體之大致1/12~1/5長度之部分切割成矩形狀，形成第2缺口部17。例如，在固設嵌入體之區域之長度尺寸為20mm以上之情形，其中第2缺口部17之長度為1.7~5.0mm左右。若將前述芯線端部7a之沿著芯線7之長度設為L1，將上述缺口部16之前後之缺口深度(鏈布長度方向之尺寸)設為d1，則為L1>d1之關係，即前述缺口部16之缺口深度d1設定為小於前述芯線端部7a之沿著芯線7之長度L1。又，前述芯線7之左右方向之寬度尺寸(粗細)w設定為小於上述第2缺口部17之左右方向之缺口深度(鏈布之左右方向之尺寸)d2。前述嵌入體10之軸部12a形成於對應於前述芯線7之前述芯線端部7a之部位。Further, in the first embodiment, as shown in Figs. 4 and 7, the side edge portion on the side where the core wire 7 of the first chain cloth 2a is added remains at the rear end of the fixed region of the above-mentioned insert body 10. The core end portion 7a cuts a portion having a length of substantially 1/12 to 1/5 of the entire region in which the embedded body 10 is fixed into a rectangular shape to form a second notch portion 17. For example, in the case where the length dimension of the region in which the embedded body is fixed is 20 mm or more, the length of the second notch portion 17 is about 1.7 to 5.0 mm. When the length of the core end portion 7a along the core wire 7 is L1, and the depth of the notch portion 16 (the dimension in the longitudinal direction of the chain fabric) is d1, the relationship of L1>d1, that is, the aforementioned The notch depth d1 of the notch portion 16 is set to be smaller than the length L1 of the core wire end portion 7a along the core wire 7. Further, the width dimension (thickness) w of the core wire 7 in the left-right direction is set to be smaller than the notch depth (the dimension in the left-right direction of the chain fabric) d2 of the second notch portion 17 in the left-right direction. The shaft portion 12a of the insert body 10 is formed at a portion corresponding to the core end portion 7a of the core wire 7.
又，在本實施例1中，如圖8所示，將形成於第1及第2鏈布2a、2b之後端緣之前述缺口部16之形成部位，設為包含 第1鏈布2a之縫製線8a之交叉位置B。Further, in the first embodiment, as shown in FIG. 8, the formation portion of the notch portion 16 formed at the end edge of the first and second link fabrics 2a and 2b is included. The intersection position B of the sewing line 8a of the first chain cloth 2a.
再者，在厚度較嵌入體10之嵌入板部11厚之被嵌入體20中，由於上述芯線7完全被埋設於被嵌入部23之內部，故即使對安裝有被嵌入體20之第2鏈布2b施加反撕裂力，被嵌入體20亦不會斷裂，從而無需於上述第2鏈布2b形成上述第2缺口部17。Further, in the embedded body 20 having a thickness thicker than the fitting plate portion 11 of the insert 10, since the core wire 7 is completely embedded in the inside of the embedded portion 23, even if the second chain to which the embedded body 20 is attached is attached The cloth 2b exerts a tearing force, and the embedded body 20 does not break, so that it is not necessary to form the second notch portion 17 in the second chain cloth 2b.
在以上之構成中，首先簡單地說明本實施例1之附有開離嵌插件之拉鏈1之閉合及分開操作。In the above configuration, first, the closing and separating operations of the slide fastener 1 with the open-release insert of the first embodiment will be briefly explained.
在閉合拉鏈1時，如前文所述，可進行以下操作：第1樞止操作，將開離嵌插件5之嵌入體10從被嵌入體20之側部嵌入，藉此樞止於該被嵌入體20；及第2樞止操作，將一般之開離嵌插件5之嵌入體10從抵接於被嵌入體20之滑件30之導入口***至鏈齒引導通路後，樞止於被嵌入體20之嵌入部。When the zipper 1 is closed, as described above, the following operation can be performed: the first pivoting operation, the insert 10 that is opened from the insert 5 is embedded from the side of the embedded body 20, whereby the pivoting is embedded The body 20; and the second pivoting operation, the insertion body 10 of the general opening and closing insert 5 is inserted into the element guide passage from the introduction port of the slider 30 abutting the body 20, and is pivoted to be embedded. The embedded portion of the body 20.
首先，若對該第1樞止操作進行說明，則在該第1樞止操作中，係將嵌入體10之樞止部12***至被嵌入體20之被嵌入部23之嵌入空間28。其次，使滑件30滑動至被嵌入體20之抵接於前述滑件保持部21之鏈布端部側之階部22的位置對接後，以樞止部12為中心，使樞止部12嵌入至大致J字狀內面24之嵌入體10朝向被嵌入體，經由狹縫27轉動，藉此，將嵌入體10之嵌入板部11從滑件30之左側之上側凸緣32a之間隙，***至滑件內部。此時，由於被嵌入體20之被嵌入部23具有大致J字形狀，故可在大致J字狀內面24之嵌入板部嵌合凹槽26處，穩定支撐嵌入體10之樞止部12。First, when the first pivoting operation is described, the pivoting portion 12 of the insert 10 is inserted into the insertion space 28 of the embedded portion 23 of the embedded body 20 in the first pivoting operation. Then, the slider 30 is slid to the position of the step portion 22 on the side of the end portion of the link holding portion 21 of the insert body 20, and then the pivot portion 12 is centered on the pivot portion 12, and the pivot portion 12 is pivoted. The insert 10 that is fitted into the substantially J-shaped inner surface 24 faces the embedded body and is rotated via the slit 27, whereby the inserting plate portion 11 of the insert 10 is separated from the left side flange 32a of the slider 30 by the left side. Insert into the inside of the slider. At this time, since the fitted portion 23 of the embedded body 20 has a substantially J-shape, the pivot portion 12 of the embedded body 10 can be stably supported at the fitting plate portion fitting groove 26 of the substantially J-shaped inner surface 24. .
第2樞止操作係使滑件30滑動至被嵌入體20之抵接於前述滑件保持部21之鏈布端部側之階部22的位置對接後，將嵌入體10之嵌入板部11從滑件30之導入口***，並將樞止部12嵌入至被嵌入體20之被嵌入部23。藉此，左右鏈齒排4、4以進行穩定嚙合的方式予以定位。In the second pivoting operation, the slider 30 is slid to the position where the stepped portion 22 of the insert body 20 abuts against the end portion 22 of the slider holding portion 21, and the inserting plate portion 11 of the insert 10 is inserted. The insertion port of the slider 30 is inserted, and the pivoting portion 12 is fitted into the fitted portion 23 of the embedded body 20. Thereby, the left and right element rows 4, 4 are positioned in such a manner as to perform stable engagement.
如此，將嵌入體10***至滑件30及被嵌入體20之被嵌入部23後，使滑件30向鏈齒嚙合方向滑動(上拉)，藉此，使左右鏈齒排4、4相互嚙合，從而閉合拉鏈1。In this manner, after the insert 10 is inserted into the slider 30 and the fitted portion 23 of the embedded body 20, the slider 30 is slid (pulled up) in the meshing direction of the fastener element, whereby the left and right fastener rows 4 and 4 are mutually Engage, thereby closing the zipper 1.
再者，在本實施例1中，在使閉合狀態之拉鏈1分開時，將向上方提起之滑件30朝被嵌入體20滑動，對接於階部22。其次，進行使由被嵌入體20之被嵌入部23支撐之嵌入體10之樞止部12通過形成於被嵌入體20之彎曲部側前端23a之狹縫27及形成於滑件30之上下側凸緣32a、32b之間之間隙，從而從被嵌入體20之側部拔脫，或通過滑件30之鏈齒引導路拔脫之2種不同拔脫操作中之任意一者，藉此，可使左右鏈帶分離。Further, in the first embodiment, when the slide fastener 1 in the closed state is separated, the slider 30 which is lifted upward is slid toward the body 20 and is butted against the step portion 22. Then, the pivoting portion 12 of the insert 10 supported by the fitted portion 23 of the embedded body 20 is passed through the slit 27 formed on the curved portion side front end 23a of the embedded body 20 and formed on the lower side of the slider 30. The gap between the flanges 32a, 32b is thereby released from either side of the body 20 or by any one of two different unplugging operations of the sprocket guide of the slider 30. The left and right chain belts can be separated.
尤其是，若本實施例1之拉鏈1為於滑件保持部21保持滑件30，且抵接於階部22之狀態，則可轉動至使左側之鏈帶相對於右側鏈帶傾斜之狀態，從而可將嵌入體10之樞止部12從被嵌入體20之嵌入空間28容易地拔脫。因此，在將樞止部12從被嵌入體20之側部拔脫之情形，相較於從滑件30之鏈齒引導路拔脫之情形，可使左右鏈帶更簡便地分離。In particular, if the slide fastener 1 of the first embodiment holds the slider 30 in the slider holding portion 21 and abuts against the step portion 22, it can be rotated to tilt the chain belt on the left side with respect to the right chain belt. Thus, the pivoting portion 12 of the insert 10 can be easily removed from the embedded space 28 of the embedded body 20. Therefore, in the case where the pivoting portion 12 is detached from the side portion of the body 20 to be inserted, the left and right chain belts can be more easily separated than when the sprocket guiding path of the slider 30 is detached.
如此，本實施例1之附有開離嵌插件之拉鏈1具有可進行藉由將嵌入體10從被嵌入體20之側部嵌入而使其樞止之第 1樞止操作，與藉由將嵌入體10經由滑件30之鏈齒引導路***至被嵌入體20而使其樞止之第2樞止操作的構造。因此，在閉合拉鏈1時，使用者可任意地選擇該等不同之2種樞止操作。又，本實施例1之拉鏈1藉由進行如上所述之第1樞止操作，相較於進行第2樞止操作之情形，更簡單地閉合拉鏈1。Thus, the zipper 1 with the open-release insert of the first embodiment has a first position that can be pivoted by embedding the insert 10 from the side of the embedded body 20. A pivoting operation and a second pivoting operation by inserting the insert 10 through the sprocket guiding path of the slider 30 into the body 20 to be pivoted. Therefore, when the zipper 1 is closed, the user can arbitrarily select the two different pivoting operations. Further, in the slide fastener 1 of the first embodiment, by performing the first pivoting operation as described above, the slide fastener 1 is more easily closed than in the case of performing the second pivoting operation.
然而，具備如上所述之構造之拉鏈雖多數適用於通常之衣服或背袋類，但近年，由於該開離嵌插件操作之容易性，而強烈希望適宜作為例如汽車之座椅或椅套等之開閉件。然而，該等之座椅或椅套不僅在車輛之行駛中，藉由上下車時之體重之移動，亦會產生使拉鏈，尤其是作為其下止擋之開離嵌插件左右分離之強大之力。然而，此時，由於拉鏈處於閉合狀態，故由於其鏈齒排處於嚙合狀態，且開離嵌插件之嵌入體及被嵌入體處於樞止狀態，因而無法簡單地進行鏈齒排之嚙合之解除，及嵌入體與被嵌入體之分開。However, although the zipper having the configuration as described above is mostly applied to a general clothes or a backpack, in recent years, it is strongly desired to be suitable as, for example, a seat or a seat cover of a car due to the ease of operation of the opening and inserting insert. Opening and closing parts. However, these seats or seat covers not only move the weight of the vehicle while driving, but also produce a strong zipper for the left and right separation of the zipper, especially as the lower stop. force. However, at this time, since the zipper is in the closed state, since the sprocket row is in the engaged state, and the insert body and the embedded body which are opened from the insert are in the pivoting state, the engagement of the sprocket row cannot be simply released. , and the embedded body is separated from the embedded body.
此時，因作用於拉鏈之強大力係經由富有可撓性之座椅或椅套等之被縫製品施加，故並不相同，且並非僅為橫拉力，由於使安裝於左右一對鏈布端部之對向側緣之嵌入體與被嵌入體分開之力係經由座椅或椅套施加至左右鏈布，故係以位於相對固定位置之嵌入體與被嵌入體為中心，對鏈布作用使將其剝離之力向斜前方轉動之力，即在本說明書中使用之反撕裂力。若參照圖8具體地進行說明，則前述之反撕裂力係沿著左右第1及第2鏈布2a、2b及加強片15 之長度方向之各後端緣傳達，集中作用於各後端緣與前述嵌入體10及被嵌入體20之各自由端部之鏈布固著側緣之交叉部A的一點。At this time, since the strong force acting on the zipper is applied through the sewn product such as a flexible seat or a seat cover, it is not the same, and is not only a lateral pulling force, but is attached to the left and right chain cloths. The force of the opposite side of the opposite side of the end portion is applied to the left and right chain cloth via the seat or the seat cover, so that the embedded body and the embedded body at a relatively fixed position are centered on the chain cloth. The force that causes the force to peel it to rotate obliquely forward, that is, the tearing force used in the present specification. As will be specifically described with reference to Fig. 8, the aforementioned tearing force is along the left and right first and second chain fabrics 2a, 2b and the reinforcing sheet 15. The rear end edges of the longitudinal direction are collectively applied to one point of the intersection portion A of each of the rear end edges and the end portions of the insert body 10 and the insert body 20 which are fixed by the end portions.
本發明係著眼於藉由使集中作用於前述交叉部A之強大之反撕裂力，在沿著各鏈布2a、2b之後端緣傳達之中途，分散成2段以上，從而可減少實際傳達至前述交叉部A之反撕裂力，並於各鏈布2a、2b之後端緣配置有前述反撕裂力之減低機構。作為該反撕裂力之減低機構，於各鏈布2a、2b之後端緣具有含1個以上折曲部之沿著2條以上之直線切割之缺口部16。根據本實施例1，前述缺口部16被切割成矩形狀。該缺口部之形狀並不受限於矩形狀，例如如圖9所示之實施例2般，亦可為具有1個折曲部之階段狀。折曲部只要為將2條直線改變角度折曲者即可，但較佳為將其2條直線折曲為直角或銳角。The present invention focuses on the fact that the strong rip-off force concentrated on the intersection portion A is dispersed in two or more stages along the end edges of the respective links 2a and 2b, thereby reducing the actual conveyance. The rip-removing force to the intersection portion A is disposed at the end edge of each of the fastener fabrics 2a and 2b. As the mechanism for reducing the tearing force, the end edge of each of the fastener fabrics 2a and 2b has a notch portion 16 which is cut along two or more straight lines including one or more bent portions. According to the first embodiment, the notch portion 16 is cut into a rectangular shape. The shape of the notch portion is not limited to a rectangular shape. For example, as in the second embodiment shown in FIG. 9, it may be a stepped shape having one bent portion. The bent portion may be any one that bends the two straight lines at an angle, but it is preferable to bend the two straight lines into a right angle or an acute angle.
在本實施例1中，若於各鏈布2a、2b之後端緣形成矩形狀之缺口部16，則於例如圖8所示之座椅或椅套等之被縫製品8，沿著縫製線8a縫製拉鏈1。前述縫製線8a橫切前述缺口部16，拉鏈1係藉由縫紉線縫製於被縫製品8。因此，施加至被縫製品8之反撕裂力在經由前述縫紉線，沿著鏈布2之後端緣傳達後，到達至與開離嵌插件5之交叉部A。In the first embodiment, when the rectangular notch portion 16 is formed at the end edge of each of the fastener fabrics 2a and 2b, the sewn product 8 such as the seat or the seat cover shown in Fig. 8 is along the sewing line. 8a sewing zipper 1. The sewing line 8a crosses the notch portion 16, and the zipper 1 is sewn to the workpiece 8 by a sewing thread. Therefore, the tearing force applied to the workpiece to be sewn 8 reaches the intersection A with the opening and closing insert 5 after being conveyed along the trailing edge of the fastener fabric 2 via the aforementioned sewing thread.
因此，在縫製線8a與前述缺口部16交叉時，在缺口部16之內部具有接縫時，前述反撕裂力不是從該接縫直接傳達至鏈布2，而是通過鄰接於缺口部16之接縫部，沿著鏈布2之後端緣傳達。該情形，反撕裂力亦沿著鏈布2之後端緣 傳達，但由於在傳達中途存在缺口部16之靠近開離嵌插件5之折曲部16a，故在該折曲部16a中，藉由從前述接縫部傳達之反撕裂力變形成直線狀。Therefore, when the sewing line 8a intersects with the notch portion 16, when the seam is provided inside the notch portion 16, the tearing force is not directly transmitted from the seam to the chain cloth 2, but is adjacent to the notch portion 16 The seam portion is conveyed along the trailing edge of the chain fabric 2. In this case, the tearing force is also along the trailing edge of the chain fabric 2 However, since the bent portion 16a of the insert 5 is opened in the middle of the conveyance, the bent portion 16a is linearly formed by the tearing force transmitted from the joint portion. .
此時，前述反撕裂力之一部分被用在為使前述折曲直線部直線狀拉伸變形之變形力，藉此，殘留之反撕裂力被直接傳達至開離嵌插件5。即，由於經由縫紉線傳達至鏈布2之反撕裂力在前述折曲直線部被分散，其一部分傳達至開離嵌插件5，故因起初產生時之反撕裂力減少，並傳達至開離嵌插件5，因此，使鏈布2與加強片15之向拉伸方向之伸展量亦減少，加強片15與開離嵌插件5之間之偏移量亦減少，從而不會有在其間剝離之情形。此處，藉由增減上述折曲部16a之數，亦可增減分散數，從而可調整傳達至開離嵌插件5之反撕裂力。At this time, one of the aforementioned tearing forces is used for the deformation force for linearly stretching and deforming the bent straight portion, whereby the residual tearing force is directly transmitted to the opening and closing insert 5. That is, since the tearing force transmitted to the chain fabric 2 via the sewing thread is dispersed in the above-mentioned bent straight portion, a part thereof is transmitted to the opening and closing insert 5, so that the tearing force at the time of initial generation is reduced and transmitted to Opening away from the insert 5, therefore, the amount of extension of the chain cloth 2 and the reinforcing sheet 15 in the direction of stretching is also reduced, and the offset between the reinforcing sheet 15 and the opening and closing insert 5 is also reduced, so that there is no The situation of peeling off during this period. Here, by increasing or decreasing the number of the bent portions 16a, the number of dispersions can be increased or decreased, and the tearing force transmitted to the opening and closing insert 5 can be adjusted.
在本實施例1中，如圖3所示，除前述缺口部16以外，在嵌入體10之形成區域之第1鏈布2a之鏈齒排形成側緣部，形成有第2缺口部17。其由於在前述鏈齒排形成側緣部嵌入體10之嵌入板部11較薄，且沿著該嵌入板部11之鏈齒排形成側緣部添設之芯線7厚度大於鏈布2a、2b之厚度，故包覆該芯線7之嵌入板部11之樹脂厚度較其他之嵌入板部11為極薄。其結果，包覆芯線7之嵌入板部11之部分強度比其他部分更弱體化，若作用上述反撕裂力，則該弱體化之部分容易斷裂，從而無法發揮作為開離嵌插件之功能。因此，在本實施例1中，如上所述，於嵌入體10形成有第2缺口部17。In the first embodiment, as shown in FIG. 3, in addition to the notch portion 16, the second notch portion 17 is formed in the side edge portion of the first chain cloth 2a in the region where the insert body 10 is formed. The inserting plate portion 11 in which the side edge portion of the fastener element is formed is thinner, and the core wire 7 which is added along the side edge portion of the element row of the inserting plate portion 11 is thicker than the chain cloth 2a, 2b. Since the thickness is such that the thickness of the resin covering the insert portion 11 of the core wire 7 is extremely thinner than that of the other embedded plate portions 11. As a result, the strength of the portion of the embedded plate portion 11 covering the core wire 7 is weaker than that of the other portions. When the tearing force is applied, the weakened portion is easily broken, and the function as the open-release insert cannot be exhibited. Features. Therefore, in the first embodiment, as described above, the second notch portion 17 is formed in the insert body 10.
又，在本實施例1中，在橫跨嵌入體10之上述嵌入板部11與上述凸條部13之交界之第1鏈布2a的三部位之對應部位，形成3個通孔9，且在對應於橫跨被嵌入體20之大致J字狀之被嵌入部23與加強部25之交界之部位之第2鏈布2b上，形成有1個通孔9，又，該第2鏈布2b在通過前述通孔9之直線上，即對應於上述加強部25之部位形成有2個通孔9。再者，在本實施例1中，由於上述第2缺口部17僅形成於第1鏈布2a，且被嵌入體20之滑件保持部21及大致J字狀之被嵌入部23具有充分之厚度，故由於能夠確保可耐使用之強度，因而未設置度2缺口部17。但亦可設置第2缺口部17。Further, in the first embodiment, three through holes 9 are formed in the corresponding portions of the three portions of the first chain cloth 2a that straddle the boundary between the insertion plate portion 11 and the ridge portion 13 of the insert body 10, and One through hole 9 is formed in the second chain cloth 2b corresponding to a portion of the substantially J-shaped embedded portion 23 and the reinforcing portion 25 that straddles the embedded body 20, and the second chain cloth is further formed. 2b is formed with two through holes 9 on a straight line passing through the through hole 9, that is, a portion corresponding to the reinforcing portion 25. Further, in the first embodiment, the second notch portion 17 is formed only in the first chain cloth 2a, and the slider holding portion 21 and the substantially J-shaped embedded portion 23 of the embedded body 20 are sufficient. Since the thickness is small, the notch portion 17 of the degree 2 is not provided because the strength that can withstand the use can be ensured. However, the second notch portion 17 may be provided.
在本實施例1中，如上所述，在對第1鏈布2a最強地作用上述反撕裂力之部位，設置前述第2缺口部17，藉此，使嵌入體10於第2鏈布2b一體化成形時，由於將前述第2缺口部17完全埋入嵌入體10之樹脂，使該第2缺口部17之部分並無與第2鏈布2b及加強片15之接合部，故第2缺口部17之部分強度增加，假設即使作用有上述反撕裂力，亦不會使該部分斷裂。又，如上所述，於第1及第2鏈布2a、2b形成通孔9，藉此，使將加強片15之一部分之材料通過各通孔9而接合於第1及第2鏈布2a、2b之正反面之加強片15予以連結，從而提高各鏈布2a、2b與加強片15之接合強度。In the first embodiment, as described above, the second notch portion 17 is provided at a portion where the first chain cloth 2a is most strongly applied to the rip tearing force, whereby the insert body 10 is placed on the second chain cloth 2b. In the integrated molding, the second notch portion 17 is completely embedded in the resin of the insert 10, so that the portion of the second notch portion 17 does not have a joint portion with the second link 2b and the reinforcing sheet 15, so the second portion The strength of the portion of the notch portion 17 is increased, and it is assumed that the portion is not broken even if the above-described tearing force is applied. Further, as described above, the through holes 9 are formed in the first and second link fabrics 2a and 2b, whereby the material of one of the reinforcing sheets 15 is joined to the first and second link fabrics 2a through the respective through holes 9. The reinforcing sheets 15 on the front and back sides of 2b are joined to increase the joint strength between the respective link fabrics 2a and 2b and the reinforcing sheets 15.
其次，參照圖式，說明本發明之實施例2之附有開離嵌插件之拉鏈。此處，圖9係顯示本實施例2之附有開離嵌插 件之拉鏈之開離嵌插件安裝部位的重要部分之正視圖。又，圖10係顯示將該拉鏈縫製於被縫製品時之開離嵌插件安裝部位之重要部分之正視圖。再者，在以下說明中，在本實施例2中，對與上述實施例1實質性相同之構件及構成部，使用與實施例1相同之符號及名稱。因此，省略該等構件之詳細說明。Next, a zipper with an open-release insert attached to Embodiment 2 of the present invention will be described with reference to the drawings. Here, FIG. 9 shows the opening and detaching insertion of the second embodiment. A front view of the zipper of the piece that is separated from the important part of the mounting portion of the insert. Further, Fig. 10 is a front view showing an important part of the attachment opening portion of the insert when the zipper is sewn to the object to be sewn. In the following description, in the second embodiment, the same reference numerals and names as those in the first embodiment are used for the members and the components substantially the same as those of the first embodiment. Therefore, a detailed description of the components will be omitted.
本實施例2之附有開離嵌插件之拉鏈101，與上述實施例1之附有開離嵌插件之拉鏈1之不同之構造有以下之(1)、(2)、(3)。The zipper 101 with the detaching insert is attached to the second embodiment, and the following (1), (2), and (3) are different from the zipper 1 with the detachable insert of the first embodiment.
(1)經由階差122連續形成於被嵌入體120之滑件保持部121之被嵌入部123並不形成為上述實施例1所示之大致J字狀，而是將外觀形成為具有垂直部123a與水平部123b之大致L字狀。沿著該垂直部123a與水平部123b之內面，挖有連續之大致L字狀之凹槽127。前述垂直部123a之凹槽127a，與上述實施例1之使嵌入體10之嵌入板部11嵌入之被嵌入體20的形成於滑件保持部21之嵌入板部嵌合凹槽26相同，與滑件保持部121之嵌入板部之嵌合凹槽127c連通。(1) The embedded portion 123 continuously formed in the slider holding portion 121 of the body 120 by the step 122 is not formed in the substantially J shape as shown in the above-described first embodiment, but is formed to have a vertical portion. 123a and the horizontal portion 123b are substantially L-shaped. A continuous substantially L-shaped groove 127 is dug along the inner surface of the vertical portion 123a and the horizontal portion 123b. The groove 127a of the vertical portion 123a is the same as the fitting plate portion fitting groove 26 formed in the slider holding portion 21 of the insert body 20 in which the inserting plate portion 11 of the insert body 10 is fitted in the first embodiment, and The fitting recess 127c of the inserting plate portion of the slider holding portion 121 communicates.
(2)嵌入體110之鏈布端側之樞止部112如上述實施例1般，係由不具有軸部12a，一體形成於嵌入板部111之端部，且一端從鏈布端向外側突出之周圍具有扣合面之小板片所構成。前述嵌入板部111及包含前述小板片之樞止部112之正反面具有連續之同一平面，其厚度設定為小於大致L字狀之凹槽127及前述嵌入凹槽127c之槽寬度(槽之厚 度尺寸)。再者，在上述被嵌入體120之大致L字狀之凹槽127中，前述水平部123b之凹槽127b之槽深度以較前述垂直部123a之凹槽127a之槽深度深而形成，且呈使前述嵌入體110之包含前述小板片之樞止部112自由嵌入(freely fit)之形狀，從而構成該水平部123b之凹槽127b可轉動地支撐前述樞止部112之本發明之嵌入空間。(2) The pivoting portion 112 of the chain end side of the insert body 110 is integrally formed on the end portion of the inserting plate portion 111 without the shaft portion 12a as in the first embodiment, and one end is extended from the end of the chain fabric to the outer side. It is composed of small plates with protruding surfaces around the protrusions. The front and back surfaces of the inserting plate portion 111 and the pivoting portion 112 including the small plate have a continuous same plane, and the thickness thereof is set to be smaller than the groove width of the substantially L-shaped groove 127 and the insertion groove 127c (the groove thick Degree size). Further, in the substantially L-shaped groove 127 of the embedded body 120, the groove depth of the groove 127b of the horizontal portion 123b is formed deeper than the groove depth of the groove 127a of the vertical portion 123a, and The pivoting portion 112 of the insert body 110 including the small plate piece is freely fit, so that the groove 127b of the horizontal portion 123b rotatably supports the embedded space of the present invention of the pivot portion 112. .
(3)分別形成於配置開離嵌插件105之側之第1及第2鏈布102a、102b之端緣的反撕裂力減低機構的缺口部116之缺口形狀並非如上述實施例1所示為矩形狀，而被設為具有鏈布端緣在與開離嵌插件105相反側，經由1個階部階段狀地上升之折曲部與直線之形狀。(3) The notch shape of the notch portion 116 of the tearing force reduction mechanism formed at the edge of the first and second link fabrics 102a and 102b on the side where the insert 105 is separated from the insert 105 is not as shown in the above-described first embodiment. It is a rectangular shape, and it is set as the shape of the bending part and the straight line which the edge of the edge of the chain fabric is the side which opened on the opposite side from the insert insert 105, and the 1st step is raised in the stage.
在具備以上之與實施例1不同之構造(1)、(2)、(3)之實施例2之附有開離嵌插件之拉鏈101中，藉由上述第1樞止操作，將該附有開離嵌插件之拉鏈101閉合時，亦與上述實施例1相同，操作滑件30(參照圖5及圖6)，使其沿著鏈齒排4，滑動至抵接於被嵌入體120之上述階部22為止。其次，將嵌入體110之樞止部112嵌入至形成於大致L字狀之上述嵌入部123之水平部123b之凹槽127b後，以樞止部112為中心，使嵌入體110向被嵌入體120轉動。此時，同時以使嵌入體110之設置於鏈齒排側之端部之嚙合部14，越過滑件30之導入口的方式，將嵌入體110之嵌入板部111插通至滑件30之左側之上下側凸緣32a、32b間之間隙。此處，使滑件30滑動至未圖示之上止檔部側，與左右之鏈齒排4、4嚙合，從而閉合拉鏈。In the zipper 101 with the open-release insert attached to the second embodiment having the structures (1), (2), and (3) different from the above, the first pivoting operation is used to attach the zipper 101. When the zipper 101 having the detaching insert is closed, as in the first embodiment, the slider 30 (see FIGS. 5 and 6) is operated to slide along the element row 4 to abut against the body 120. Up to the above step 22. Next, after the pivoting portion 112 of the insert 110 is fitted into the recess 127b formed in the horizontal portion 123b of the substantially L-shaped embedded portion 123, the embedded body 110 is oriented toward the embedded body centering on the pivoting portion 112. 120 turns. At this time, the engaging portion 14 of the insert body 110 is inserted into the slider 30 so that the engaging portion 14 of the end portion of the insert body 110 provided on the element row side passes over the introduction port of the slider 30. A gap between the upper and lower lower flanges 32a, 32b on the left side. Here, the slider 30 is slid to the upper stopper portion side not shown, and meshes with the left and right element rows 4, 4, thereby closing the slide fastener.
又，在實施例2中，亦可藉由與通常之附有開離嵌插件之拉鏈相同之上述第2樞止操作，閉合拉鏈。即，首先，使滑件30沿著鏈齒排4滑動至抵接於被嵌入體120之上述階部22為止。其次，將嵌入體110從滑件30(參照圖5及圖6)之導入口***，經由鏈齒引導路嵌入至形成於被嵌入體120之上述水平部123b之凹槽127b。此時，嵌入體110之嵌入板部111***至滑件30之左側之上下側凸緣部32a、32b間之間隙。僅以上述之第2樞止操作，可以嵌入體110之樞止部112為中心，對於被嵌入體120相對可轉動地支撐嵌入體110。Further, in the second embodiment, the zipper may be closed by the second pivoting operation which is the same as the zipper which is usually provided with the opening and closing insert. That is, first, the slider 30 is slid along the element row 4 until it abuts against the step portion 22 of the body 120 to be embedded. Next, the insert body 110 is inserted from the introduction port of the slider 30 (see FIGS. 5 and 6), and is fitted into the groove 127b formed in the horizontal portion 123b of the body 120 to be inserted via the element guide path. At this time, the fitting plate portion 111 of the insert body 110 is inserted into the gap between the upper left upper flange portions 32a and 32b of the slider 30. Only in the second pivoting operation described above, the pivoting portion 112 of the embedded body 110 can be centered, and the embedded body 110 can be relatively rotatably supported by the embedded body 120.
儘管為如此之簡單構造，但除可藉由第1及第2之兩種樞止操作，簡單地將嵌入體110樞止於被嵌入體120以外，在本實施例2中亦與上述實施例1相同，由於形成有反撕裂力減低機構的缺口部116，故在對拉鏈101之開離嵌插件安裝側之鏈布端部施加強大之反撕裂力時，加強片15與嵌入體110之間不會產生剝離現象。在上述實施例1中，包含缺口部起端及末端具有4段折曲部，但在本實施例2中，缺口部116之折曲部包含缺口起端僅有2段。因此，若在該實施例2中，對前述鏈布端部施加撕裂方向之強大之反撕裂力，則該力會經由缺口起端傳達至中途之階段狀折曲部。此時，在缺口起端及中途之階段狀各折曲部，前述強大之反撕裂力會分散，對最終之嵌入體110與鏈布端緣之交叉部C施加經減少之反撕裂力，從而如上所述，防止加強片15與嵌入體110之間之剝離現象。Although it is such a simple configuration, in addition to the pivoting operation of the first and second types, the embedded body 110 is simply pivoted outside the embedded body 120, and in the second embodiment, the embodiment is also the same as the above embodiment. In the same manner, since the notch portion 116 of the tearing force reduction mechanism is formed, the reinforcing sheet 15 and the insert body 110 are applied when a strong tearing force is applied to the end portion of the fastener tape 101 which is opened from the insert mounting side. There is no peeling between them. In the first embodiment described above, the end portion and the end portion of the notch portion have four bent portions. However, in the second embodiment, the bent portion of the notch portion 116 includes only two slit ends. Therefore, in the second embodiment, when a strong rip-off force in the tearing direction is applied to the end portion of the chain fabric, the force is transmitted to the intermediate-shaped step-shaped bent portion via the notched end. At this time, the strong tearing force is dispersed at the bent portions at the beginning and the middle of the notch, and the reduced tearing force is applied to the intersection portion C between the final insert 110 and the end edge of the chain fabric. Thus, as described above, the peeling phenomenon between the reinforcing sheet 15 and the embedded body 110 is prevented.
